One day after eight people were shot at a Brooklyn house party, five more people were shot and wounded at another house party just a few miles away early Sunday.
Police said four men and a woman were shot near Nostrand Avenue and Fenimore Street in Prospect Lefferts Gardens around 12:30 a.m. Sunday.
All five victims were taken to the hospital, and police said at least one victim was in serious condition.
Neighbors said the gunfight started at a barbecue and then the shooters chased each other to the next block. Police said the gunmen fired over 40 shots.
Witnesses said the gunfire sent about 30 people running down Nostrand Avenue.
The gunshots, which were captured on cellphone video by a neighbor, at first reminded locals of fireworks.
"I thought it was the Fourth of July," said a neighbor. "I couldn't go near the window because I was kind of scared myself."
"At first, when I first heard this, I thought, is this shots or firecrackers? But when I heard it again, it was not firecrackers. It was shots," said another.
Locals said they were saddened by the violence.
"I thought the neighborhood kind of calmed down. It was like that earlier in the '80s, like the late '80s, early '90s," said a neighbor.
On Sunday, police said they expected three surveillance cameras on the corner of Nostrand Avenue and Fenimore Street to provide more clues.
By Sunday evening, no arrests had been made in connection with the shooting.
Meanwhile, three men remained in police custody on Sunday following the previous day's deadly shooting in East New York, Brooklyn.
Police said at least 20 shots were fired after two men bumped into each other during a crowded house party at 325 Wyona Street early Saturday morning.
Donzell Rogers, 20, was killed and seven other people were hospitalized with gunshot wounds.
The three men in custody were spotted running from the scene, but they had not been charged or arrested by Sunday evening.
Police were looking into the possibility that the Saturday shooting was gang-related.
Local leaders warned the violence will only get worse this summer if more attention is not paid to the city's youth.
"I think the police have a terrible challenge and the community is being neglected," said the Reverend Gerard Cantalupo of Full Gospel Tabernacle. "The mayor can say all he wants that crime is down, but violent crime is among the youth and if you neglect them you provoke them."
